Patent number: 7141738Abstract: A re-enterable enclosure for a splice between cables, comprises two cover members with internal walls that are configured to form a cavity for enclosing the cable splice when the cover members are engaged with each other in a closed position. At least one of the cover members also has internal walls that are configured to define containment spaces which at least partly surround the cavity. In use, those containment spaces may contain sealant material. At least one internal wall in one cover member can telescope into a containment space in the other cover member so that, if sealant material is contained therein, it will be compressed when the cover members are engaged with each other in the closed position. By changing the containment spaces that are used to contain sealant material, different levels of protection against humidity can be provided for the cable splice in the cavity.Type: GrantFiled: February 2, 2004Date of Patent: November 28, 2006Assignee: 3M Innovative Properties CompanyInventors: Yvonnick Marsac, Christophe Desard
